Explosion-proof equipment test system under action of explosion multi-physical field

Abstract

The invention provides an explosion-proof equipment test system under the action of an explosion multi-physics field, the damage characteristics of the explosion multi-physics field can be tested at the same time, and data support is provided for accurate evaluation of the explosion-proof performance of the explosion-proof equipment. The test system comprises a test platform, an explosion transient optical test unit, a shock wave overpressure test unit, an explosion driving fragment test unit, an explosion mechanical work test unit, an explosion seismic wave test unit, an explosion transient temperature field test unit, an explosion noise test unit, an explosive and to-be-tested explosion-proof equipment. The test platform comprises a mounting platform, a base, a support frame and an annular target, the table top of the mounting platform is used as a test plate for placing the explosive and explosion-proof equipment to be tested, and the explosion-proof equipment covers the explosive; the annular target is of a semicircular structure formed by connecting more than two arc-shaped authentication targets in sequence; the annular target is supported on the mounting platform through the support frame so that the explosive on the mounting platform is positioned at the circle center of the annular target.

Description

technical field [0001] The invention relates to an explosion-proof equipment testing system, in particular to an explosion-proof equipment testing system under the action of explosion multi-physical fields, belonging to the technical field of public safety. Background technique [0002] Explosion multiphysics effects refer to the effects of shock waves, explosive fragments, mechanical work, seismic waves, thermal radiation, and strong detonation noise that accompany typical explosives during explosions. The current test method in the field of explosive testing is simple, and generally only considers whether the structure is broken by the naked TNT explosive. Typical examples are "GA871-2010 Explosion-Proof Tank", "GA872-Explosion-Proof Ball"; or only consider whether there are debris flying out, such as "GA69-2007 Explosion-Proof Blanket" test standard. However, there are many damage elements produced by the explosion, and the impact injury, fragment injury, throw injury, h...

Problems solved by technology

Among them: under the action of overpressure, negative pressure and dynamic pressure, the shock wave will produce pressure difference, implosion effect, rupture effect, etc. in the parenchyma and hollow organs, which will cause damage in the body; high-speed fragments produced by the explosion can cause damage to the body The blunt rubbing or penetration of the tissue will seriously damage the integrity of the body's organs and tissues, causing the body's tissues to lose their original functions; the mechanical work will produce an inertial throwing effect, causing the organism to suffer from falling and impacting, which will directly cause external damage to the bones or soft tissue organs; the explosion seismic wave The generated shear wave has a large wavelength and strong amplitude, and it only propagates along the ground surface, which can cause strong damage to the doors, windows and walls of the building, and then bring unsafe hidden dangers to the personnel and property in the building; Radiation, which will cause a series of secondary reactions such as stress ulcers, systemic inflammatory response syndrome, and even sepsis and multiple organ dysfunction syndrome; the explosion produces a high sound pressure level detonation effect, which can cause organisms Perforation of the tympanic membrane, fracture of the ossicular chain of the middle ear, and acoustic damage to the most sensitive parts of the central auditory system
